The Web User Interface Usage
Our support articles for the Yealink SIP-T48U focus on accessing features directly from the phone's user interface.
You can also access and control features from a web browser using the Web User Interface. It provides more comfortable navigation, additional utilities and options, diagnostics tools, and advanced features such as Forward or DND authorized numbers.
IP Address and Login Credentials
To access the web user interface you need to know two things:
- The IP address of the phone.
To find out the IP address press the OK key when the phone is idle.
You can also select Menu from the idle screen and then select Status>General.
If your local network is using a DHCP server, the IP address is configured automatically when your phone is initially powered on. If the phone cannot obtain the IP address automatically you may need to configure the network settings manually.
- The phone's current administrator or user login credentials.
The default administrator credentials are “admin" (case-sensitive) for both the user name and password.
The default user credentials are “user" (case-sensitive) for both the user name and password.
When we initially provision your phone we usually change these passwords. If the default passwords are not accepted and you are an existing client please contact us for assistance.
Enabling the Web Server on the Phone
The web server feature on your conference phone may be disabled. To allow the Web User Interface access to your phone the web server needs to be enabled!
To enable the web server:
- Select Menu from the idle screen and navigate to Setting>Advanced Setting.
- If prompted for a password enter the default password ("admin") or the current phone's admin password.
- Navigate to Network>Web Server.
- Depending on your network requirements enable the HTTP or HTTPS option to allow access to the Web User Interface with either the HTTP or HTTPS protocol (HTTPS offers more security.)
When you don't plan on using the Web User Interface, you can simply follow the same steps and disable the HTTP Status or HTTPS Status option. This will provide extra security, but you should inform your phone system administrator about doing so as he may need to be able to access your phone over the local network.
Web User Interface Access
To access the web user interface do one of the following:
- Enter the IP address in a web browser of your choice on a computer or a mobile device that is on the same network as the phone.
When prompted by the login page, enter the current administrator credentials in the username and password fields and click Confirm.
If the administrator password is not accepted, you can try entering the user credentials in both fields. This will provide you with a more limited access to some of the features of the web user interface.
- If enabled on your phone and supported by your browser, you can skip the login page by entering a URL request in your browser.
To do so you use the format “https://username:password@phoneIPAddress” (for example, https://admin:email@example.com).
If all details are entered correctly your browser will open the Status page of the web user interface.
For security, after accessing the web user interface you can change the admin password from Security>Password. You can also change it from the phone user interface by selecting Menu in the idle screen and navigating to Advanced Settings>Set Password.
Your computer or mobile device need to be on the same network as the phone. This means a remote connection is not possible.
If you are unable to connect even when in the same office or location as the phone try one of the followings:
- Make sure to enable the web server on the phone, as explained above.
- If the phone is using a Wi-Fi network without a physical network connection make sure that Wi-Fi is enabled and connected properly. See more information here.
- Try rebooting the phone and your main router.
- Try using your browser in private or incognito mode or use a different web browser.
- If you are using a browser with an ad-blocking feature or if the browser has an ad-blocking extension/add-on, the Advanced Account or Network settings may not be accessible. To fix this disable the blocking for the web page of the Web User Interface.
- If none of the above help, you can try to connect a network cable directly between the phone's PC port and a computer or plug the phone directly into your router.
